Ke kila kila 17-4PH-SUS630
Nā inoa kālepa maʻamau:17-4ph,S51740,SUS630,0Cr17Ni4Cu4Nb,05Cr17Ni4Cu4Nb,W. Nr./EN 1.4548
ʻO ka 17-4 stainless he mea paʻakikī martensitic stainless e hui pū ana i ka ikaika kiʻekiʻe me ke kūpaʻa corrosion o ke kila kila.Hoʻokō ʻia ka paʻakikī ma ka manawa pōkole, maʻalahi haʻahaʻa haʻahaʻa.ʻAʻole like me nā kila kila martensitic maʻamau, e like me ke ʻano 410, 17-4 hiki ke weldable.ʻO ka ikaika, ka pale ʻana i ka corrosion a me ka hana maʻalahi hiki ke hana i ka 17-4 stainless i mea kūʻai kūʻai maikaʻi no nā kila kalapona ikaika kiʻekiʻe a me nā māka kulika ʻē aʻe.
Ma ka hopena e mālama ana i ka mahana, 1900 ° F, he austenitic ka metala akā e hoʻololi ʻia i kahi ʻano martensitic haʻahaʻa-carbon i ka wā e hoʻoluʻu ai i ka lumi wela.ʻAʻole paʻa kēia hoʻololi a hiki i ka hāʻule ʻana o ka mahana i 90°F.ʻO ka hoʻomehana ʻana i nā mahana o 900-1150 ° F no hoʻokahi a ʻehā mau hola e hoʻoikaika ai ka ua.ʻO kēia hoʻomaʻamaʻa paʻakikī hoʻi e hoʻonāukiuki i ke ʻano martensitic, hoʻonui i ka ductility a me ka paʻakikī.

17-4PH Bar & Kookoo
Nā lāʻau pōʻai/Paʻa paʻa/Paʻa Hex,Nui Mai 8.0mm-320mm, Hoʻohana ʻia no nā bolts, fastners a me nā ʻāpana ʻokoʻa ʻē aʻe
17-4PH Uea Hoopaa
Hoʻolako ʻia ma ka uea kuʻi a me ka uea puna ma ke ʻano coil a ʻoki ʻia ka lōʻihi.
17-4PH Puna
Spring me e like me nā mea kūʻai aku kiʻi a kikoʻī paha
17-4PH pepa a me ka pā
ʻO ka laulā a hiki i 1500mm a me ka lōʻihi a hiki i 6000mm, Mānoanoa mai 0.1mm a 100mm.

Hiki ke hana ʻia ka nui maʻamau a me ka nui i hoʻopili ʻia e mākou me ka hoʻomanawanui liʻiliʻi
17-4PH kāʻei a me ka wili
ʻO ke kūlana palupalu a me ke kūlana paʻakikī me ka ʻili ʻālohilohi AB, ka laulā a hiki i 1000mm
17-4PH Hoʻopili
17-4PH i nā ʻano Bolts, nā ʻūlū, nā flanges a me nā mea wikiwiki ʻē aʻe, e like me nā kikoʻī o nā mea kūʻai aku.
No ke aha 17-4PH ?
•E maʻalahi e hoʻololi i ka pae ikaika, ʻo ia ma o ka hoʻololi ʻana i ke kaʻina hana wela e hoʻoponoponoka hoʻololi a me ka ʻelemakule martensite
ka mālama ʻana i ka pae hoʻopaʻakikī o ka ua.
•ʻO ka pale ʻana i ka luhi a me ka pale wai.
•wiliwili:I ke ʻano o ka hoʻonā paʻa, ka ʻelemakule a i ʻole ka overageing, hiki ke welded i ka alloy ma ke ala, me ka ʻole preheating.
Inā koi ʻia ka ikaika wili kokoke i ka ikaika kila o ka ʻelemakule, a laila pono ka paʻa paʻa a me ka mālama ʻana i ka wā kahiko ma hope o ke kuʻi ʻana.
He kūpono hoʻi kēia huila no ka brazing, a ʻo ka mahana brazing maikaʻi loa ka wela o ka hopena.
•ʻO ke kūpaʻa ʻino：ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o Alloy ma mua o nā mea kila paʻakikī ʻē aʻe, ma ka wai paʻa e maʻalahi i ka erosion corrosion a māwae paha.
17-4PH kahua noi:
•ʻO nā paepae waho, ka helicopter deck, nā paepae ʻē aʻe.
•ʻOihana meaʻai.
•ʻOihana pulp a me ka pepa.
•Space (puhu turbine).
•ʻāpana mīkini.
•ʻO nā pahu ʻōpala nuklea.
